Description of the pattern
The act of using nationalism to rally and sway the perceptions one's country (or group of people) by designating an enemy. This is typically a diversionary tactic in order to take away unwanted attention and or to win popularity.
Why the pattern is good (i.e. bad)
This high level method aids in creating tunnel vision for those susceptible as well as grants solidarity for the person providing the energy. When an individual (or nation) has this type of hold on the people, things run smooth- there is also very little questioning.
How it works
Using an event or an appeal to common ground to ignite extreme solidarity.
9/11's events has created one of the biggest examples of Ultra-nationalism in history thus far. The patriot act came into full affect shortly after- something that the American society, otherwise, would have said no to- a direct result of Ultra-nationalism.
